Exhaust Gas Recirculation System Is the main problem here. the other code P0118 may be a bad temprature sensor or your thermostate needs to be changed. Last it could be a weak water pump.
So what is an EGR system and how does it work? EGR stands for Exhaust Gas Recirculation, and as its name implies, this system allows exhaust gasses from your car to be re-circulated into the engine, helping to reduce emissions. These systems are mostly comprised of the EGR valve, a DPFE (Delta Pressure Feedback EGR) sensor, hoses, a vacuum regulator, some vacuum lines, wiring, the computer and the exhaust tube leading to the valve itself.
The car's wiring can be tested in the normal fashion by looking for broken and lose wire, and all vacuum lines can be checked easily for cracks, leaks and correct routing.
The last thing i would then check is the the EGR valve, EGR vacuum regulator and DPFE sensor (or similar flow sensor).
I hope this helps and good luck

The EVAPORATIVE PURGE CONTROL VALVE is located under the hood usually behind or near the back of the headlights. It it on the top of the Evap Charcol Cannister ( shaped something like a Quaker Oats box ) . Basically does not allow fuel vapors to escape into the air. Te purge valve will recycle the vapors through a charcol filter and sent to be reused as fuel., Problem could be caused by excessive fuel in the cannister, or the solenoid, or wiring, etc back to the computer.. Requires a lot of diagnosing. Hope this helps.

Yes. Look on the brake pedal lever under the dask. When the brake pedal is pressed the switch is engaged. This is easy enough to replace. If you see two switches, the other one is probably a switch to disable the cruise control.
